' LOUIS D.OAILLAT, OF PARIS, FRANCE.

MANUFACTURE OE PASTEBARD BOXES.

SPECIFICATION forming part of Letters Patent No. 270,740, dated January16, 1883.

Application filed November 27,'188'2. (Model.) Patented in France August5,1882; in Belgium August 9, 1882; in England August 9, 1882, and inGermany August l5. 1882.

To all whom it may concern Beit known that I, LoUIs DIEUDONN CML- LAT, acitizen of France, residing at Paris, Department of the Seine, Republicof France, have invented certain new and useful Improve-l ments in theManufacture of Pasteboard Boxes 5 and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accom panying drawings, and toletters or figures of reference marked thereon, which forni a part ofthis specification. f

The object of this invention is to manufacture boxes provided with aseat for the lid from a single piece of paper-board, straw-board, orpulp or wood, or other pulp or paste, substantially as hereinafter morefully described, and as specifically pointed out in the claims.

In the accompanying drawings, Figure`l is avertical section of a boxconstructed as usual, and having a seat for the lid. Fig. 2 is a likesection of a'box constructed according to my invention; Figs. 3 and 4show in section a d-ie and followers for making my improved boxes, andFigs. 5 and 6 show in elevation and plan a blank for a cylindrical box-.its throat.

and its lid.

Like letters of reference indicate like parts in the above iigures ofdrawings.

Boxes having a portion of their body enlarged to form a throat and vseatfor the lid have heretofore been made of several pieces--A namely, a,strip, a, that constitutes the body of the box; a strip, b, thatconstitutes the enlargement thereof, so as to form a throat, c,

and a seat, d, for the lid, and a disk, e, that forms its bottom. Thelid, also, of this class of boxes is usually made of two piecesa disk,e', that forms its top, and a strip,f, that forms These several parts ofthe box and lid are united by means of strips of paper, or

by means of a lining` g, and outside covering h. The object of thisinvention is t'o make the box and lid each of a single piece, andpreferablywith projecting top and bottom.

I am aware that boxes are made from paper or straw board, or from pulpor other paste or stock, of a single piece by compression but such boxesare, so far as I know, devoid of the enlargement l), forming a throat,c, and a seat, d, for the lid.

I am also aware that `lids have been made for boxes by compression of asingle piece, and I do not desire to claim such, broadly.

In carrying out my invention I take for a cylindrical box a cylindricalblank, B, of paper or straw board or pulp, of sufcient thickness toobtain the box. This is softened by moistening it and placed in a die,D, Fig. 3, of appropriate form, having the enlarged cavity D' and thethroat D2. The box is then shaped by compression, by means of thefollower F, of uniform diameter. The lid of the box is also made in adie of appropriate form, and by compression by means ot' a follower.

In order to impart to the box and lid a better finish, I prefer inpractice to form the same with a top and bottom projecting slightlybeyond the body of the box and lid, and forming an annular ilange, E, atthe bottom of the box and at the top lof the lid, as shown. In order todo this by compression, a two-part die, D, is used, as shown, so thatwhen the box or lid is completed they may be removed from the die. It isevident that the same die may be used for forming both the box with itsflanged bottom, enlarged body, and throat and the lid with its flangedtop, using for the latter a blank of the same horizontal diameter asthat used for the box, butof less vertical diameter, and` a follower ofgreater diameter than that of the follower used for forming thebox-namely, of a diameter equal to that of the box and'its throat, asshown in Figs. 3, 4, 5, and 6.

Of course it will be understood that I do not limit myself tocylindrical boxes exclusively, as any other form of box provided with athroat and seat for the lid may be made equally as well, and such boxesand lids may be ornamented by any ofthe well-known means employed in thearts for such purposes. They may be painted after they are lnade, or theboard or pulp or paste from which they are made may be suitably stainedor dyed while being made, or such boxes may be otherwise ornamented.

Having thus described my invention, what I claim is- 1.'.A paper boxformed of a single piece and having part of its body ofincreasedexterior diameter to form a throat and seat for the reeeptionof the lid, said box being of uniform interior diameter, and having abottom projeetingbeyond the enlarged portion of the body to form aflange around the saine, as set forth.

5 2. A paper box formed of a single piece and having a portion of itsbody of increased diameter to form a throat and seat- 'or tbe lid, and

a bottom projecting beyond the enlarged portion of said body to form aBange around the 1o same, in combination with a lid formed also of asingle piece, and having its top projecting` beyond the neck or body ofsuch lid to form a flange around the same, substantially as described.

In testimony whereof I affix my signature in 15 presence of twowitnesses.
